Why does Prettier sometimes cause VS Code to report errors related to file deletion even when the file seems to be deleted?

VS Code's file system watcher might not immediately recognize the deletion, leading to a temporary discrepancy. Restarting VS Code usually resolves this. The error might also be a false positive from an extension that hasn't updated its file index. Try reloading the VS Code window (Ctrl+Shift+P, then type 'Reload Window').
